[2.0.60] Rail signal ghosts placed incorrectly by bots

[Jammaster]

Hello. I have an issue that's kind of a feature request. I have a X-intersection blueprint for my trains. The problem occurs when I let bots build the blueprint for me- the circled signals have a chance to flip to a different train track, depending on which one was build first by the bots

Here is the blueprint string, try a couple times and see:

Code: Select all

I don't know much, but this could be fixed by adding a checkbox in the blueprint that forces signals to be a certain way, regardless of what rails are there at the time.

Your blueprint is not symmetric and you marked the wrong signals. I have marked with arrows the two misplaced signals on your screenshot. In my testing the blueprint is built as designed every time.

Post a vanilla save that lets you reproduce the issue please and describe exactly how to do so.

I stared at this thing for too long ...
Sorry for wasting your time, you are absolutely correct. Thank you for your help! I should have known better than to think there is a bug in Factorio
